SPECIFICATION forming part of Letters Patent No. 687,280, dated November 26, 1901.

Application filed March 18, 1901. sei-in No. 51,597. Numana To all whom, it may concern:

Be it known thatl, WILLIAM SPALCKHA- VER, a citizen of the United States, residing at New York, county of Kings, and State of New York,have invented certain new and useful Improvements in DeliveryMechanisrns for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. A

This invention relates to certain improvements in printing-machines. In certain kinds of fast newspaper-printing machines the p roduct from the delivery mechanism-as, for instance, the cutting and collecting cylinderspasses into a throat or passage through which it passes as it is led out of the machine. It sometimes happens that the papers are not carried away fast enough by the tapes or other feeding-out mechanism employed,and a choke occurs in the throat.

It is the object of this invention to produce a mechanism by which choke in the delivery throat or passage may be prevented or instantly relieved if it occurs, independent and perfectly automatic means being employed to return said mechanism to its normal position after the choke isv relieved. j

With this and other objects in View the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.V

In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same parts, Figure v1 illustrates in front elevation so much of a delivery mechanism of a printing-machine as is necessary to an understanding of the invention. Fig. 2 is a view similar to Fig. 1, showing the parts in adifferent position. Fig. 31s a View similar to Fig. l, but showing the parts in a different adjustment. Fig. 4 is a side elevation, partlyin section, of the construction shown in Fig.1. Figs. 5 and 6 illustrate a modification.

In the drawings, which illustrate one embodiment of the invention, 1 indicates a frame which may be of any usual form or congu ration, and 2 and 3 indicate the ordinary cutting, folding, and collecting cylinders, to which the web is led from guide-rolls 4. Located beneath the cylinder 2 are the ordinary nipping-rolls 5, to which the product is delivered-as, for instance, by means of an ordinary tucking-blade (not shown) or in any other suitable manner.

In the construction shown in Figs. 1 to 4, inclusive, two throats or passages lead from the nipping-rolls, either of which may receive the product therefrom. In the preferred form of the construction a set of tapes 6 forms a side of one of the throats and a set of tapes 7 forms a side of the other throat. It is to be understood, however, that any other suitable construction may be substituted for the tapes, if desired. The tapes 6 pass over a roll 8 and onward to any suitable delivery-point, (not i11nstrated,) and the tapes 7 pass over a similar roll 9. interest of clearness is not shown. .The opposite sideof the throats, of which the tapes 6 and 7 form one side, include movable guides which may be varied widely in construction. In the preferred construction, however, these guides consist of sets of fingers, the set of tingers which cooperate with the tapes 6 being marked 10 and the set of fingers whichfcoperate with the tapes 7 being marked 11. The fingers 10 are mounted on a shaft 12, which is suitably supported in the frame of the machine, and the fingers 11 are mounted on a similar shaft 18.

Means are preferably provided by which when either the fingers 10 or the fingers 11 are in operative position the product coming from the nipping-rollswill be directed into the proper path. While these directing or switching means may be varied in construction, each of the fingerslO will be formed to provide a projection 14, this ,being accomplished by giving the fingers the shape shown or in any other suitable manner, and the tingers 11 will similarly be provided with projections 15. The nipping-rolls 5 consist, as usual, of a series of narrow drums or'wheels mounted on shafts, and when eitherl guide is in position the projections of its fingers will lie between the pairs of drums, thus preventing the product from being carried around the nipping-rolls.

The return run of the tapes in the.

IOO

The guides 10 and 11 are thrown into and out of position by rocking shafts 12 and 13, on which they are mounted, and these shafts will preferably be connected so that the movement of a guide into position occurs simultaneously with the movement of the other guide out of position. The shafts 12 and 13 may be rocked in any suitable manner, and the connections between the shafts to effect the simultaneous movement of the guides may be of any suitable construction. As shown, the end of the shaft 12 is provided with a casting which is formed to provide a handle 1G and an arm 17. The shaft 13 is provided with another casting, which has projecting therefrom an arm 13. The arms 17 and 18 are connected by alink 1Q. Vhen, therefore, the shaft 12 is rocked, the two guides will be operated, one being thrown into position and the other out of position. Means are provided, which may be of any suitable description, to move the guides into and out of position when choke occurs, which is apt to occur between the guide and the set of tapes with which it cooperates. In the preferred form of the construction these means consist of a rock-lever 20, pivoted to the frame of the machine at 2l. This lever maybe provided with means, as an extension 22, by which it may be operated, said extension passing through a platform 46, which is located in front of the delivery. The extension 22 is preferably arranged to be operated by the foot, and the lever 2O has connected to it a rod 23, which extends through a puppet 24, secured to the frame of the machine, and carries on its upper end an operating cross-bar 25. Between the cross-bar 25 and the puppet 24 is located a spring 26,`

which tends to normally hold the rod and lever up out of operative position. The castings, heretofore referred to as mounted on the shafts 12 and 13, are preferably provided with arms 23 and 29, and the arm which is secured to tne shaft of the guide which is in operative position is so located as to be struck by the operating-bar 25 when the lever 2O is depressed. This will rock the shaft belonging to the guide and move the guide backward away from its coacting set of tapes, so as to allow the product to drop onto the floor.

Means which are independent of the-opening means are provided for returning each guide to its operative position as soon as the operating-lever 2O has been released. In the preferred form of the 'construction these means consist of a spring or its well-known equivalent-aweight. TvVhilethespi-ingsmay be variously applied in the preferred form of the construction, the castings, before referred to as mounted on the shafts 12 and 13, are provided with arms 30 and 3l. The arm 30 has secured thereto a rod 32, which passes through a puppet 33, secured to the frame, and is provided with a collar 34. Between the collar 34 and the puppet 33 is located a spring 35, which will be compressed by the movement of the arm 30,- produced by rocking shaft 12. Similarly the arm 31 has connected to it a rod 36, which passes through a puppet 37, and is provided with a collar38, a spring 39 being located between the puppet and the collar. These spring-rods and the arms to which they are connected are preferably so arranged that when the shaft 12 is operated by its handle to throw either guide in or out of operative position the arms and springs will pass the center, and the springs will therefore hold the guides in their adjusted position. The movement of the guides produced by the lever 2O and the cross-bar 25, which is connected thereto, is not sufi-icient to cause these springs to pass the center. Itis apparent, therefore, that as soon as the rock-lever 2O is released the guides will immediately move back into operative position.

Sets of tapes 40 and 41, which may be mounted in any suitable or usual manner, cooperate with the tapes G and 7 to forward the product after it leaves the guides 10 and 1l.

In the construction shown in Figs. 5 and G a single throat only is employed. This is formed, as before, by a set of tapes, (marked 6,) and cooperating with these tapes is a movable guide formed of fingers 10. The construction corresponds in all respects with that Shown in Figs. 1 and 2, except that the rocklever 2O instead of being pivoted at one of its ends is pivoted in the middle to a bearing 42, secured to the fioor of the machine. The rod 2O is connected to an arm 43, mounted on the shaft 12, as before. The casting, which has been before described, is not used in this form of the construction, and instead of springs, which return the guide, an arm 44, carrying a weight 45, is employed.

Vhile the specific means heretofore described for carrying the invention into effect constitutes a preferred embodiment of the invention, it is to be understood that the invention is not to be limited thereto.
